Home > Guides > Faxing a mortgage application
Yes, most mortgage lenders still accept faxed applications, and many list a dedicated fax line for exactly that purpose. You send the signed application plus supporting pages, then confirm receipt with the loan officer or processor. Some lenders now prefer a secure upload portal, so check the lender's instructions first before you fax anything with financial details on it.
The application form itself comes first, signed and dated on every signature line. Lenders usually ask for the same supporting set: recent pay stubs, bank statements, tax returns, and a photo ID. If someone helped with the down payment, a signed gift letter rides along too. Put the pages in the order the lender's checklist lists them: a processor works through a stack top to bottom, and a scrambled order is how pages get missed.
Write your name and, once you have one, your loan number at the top of each supporting page. A fax can drop a page or split a stack, and a stray bank statement with no name on it is hard to file. Number the pages too, as page 1 of 12 and so on, so the receiving side can spot a gap at once.
Use the fax number printed in the lender's own application packet or on the lender's own site. Never use a number from a search ad, a message, or a third-party directory: misdirected faxes are one of the most common ways financial paperwork lands with a stranger. A short cover sheet helps: your name, loan number, page count, callback number, and a note that the pages are confidential.
Send from a private machine or a trusted service, not a shared shop copier with a public tray. Many office machines keep copies of sent pages in memory, which is fine in your own office and a risk in a public one. After sending, call or message the processor and ask two questions: did every page arrive, and are the numbers readable? If one page failed, resend that page alone rather than the whole packet.
Many larger lenders now steer applicants to a secure upload portal, and some treat portal uploads as received the moment they land, while a fax waits for someone to file it. If the instructions say portal only, faxing can slow the file down rather than speed it up. Ask the loan officer which route they log first, and follow that one. Fax stays common with brokers, credit unions, and smaller lenders, where a fax line may be the only intake route besides mail.
LetterAgent's fax service is in testing, with activation still in progress, so it is described as available in testing rather than as a same-day guarantee. You describe the fax to your AI assistant, approve the exact quoted price, and pay once through Stripe. It handles US and Canadian fax numbers only, and it cannot receive faxes. For a time-critical mortgage fax, such as one tied to a rate-lock deadline, use the lender's own route and keep the confirmation page.
